I am about ready to make the change to this type of oil change but before buying a pump, thought I would your opinions on which one to buy.

Last week, a local marine supply house had some in their monthly flyer for $59.95 and it looked OK but not knowing anything about them, decided to wait.

Somewhere on the net a few months ago, I read that some of those pumps do not work well or maybe not all all with hot oil and I prefer to change the oil while it is hot or at least very warm.

Thanks
